This habit of prayer then, recurrent prayer, morning, noon, and night, is one discriminating point in Scripture Christianity, as arising from the text with which I began, “our conversation is in heaven.” In a word, there was no barrier, no cloud, no earthly object, interposed between the soul of the primitive Christian and its Saviour and Redeemer. Christ was in his heart, and therefore all that came from his heart, his thoughts, words, and actions, savoured of Christ.
Christians … were thereby knit together in one body, different, as they were, in races, ranks, and habits, distant from each other in country, and helpless amid hostile populations. … Christians could not correspond; they could not combine; but they could pray one for another. Even their public prayers partook of this character of intercession; for to pray for the welfare of the whole Church was in fact a prayer for all the classes of men and all the individuals of which it was composed. It was in prayer that the Church was founded.
Many a man seems to have no grasp at all of doctrinal truth. He cannot get himself to think it of importance what a man believes, and what not. He tries to do so; for a time he does; he does for a time think that a certain faith is necessary for salvation, that certain doctrines are to be put forth and maintained in charity to the souls of men. Yet though he thinks so one day, he changes the next; he holds the truth, and then lets it go again. He is filled with doubts; suddenly the question crosses him, “Is it possible that such and such a doctrine is necessary?” and he relapses into an uncomfortable sceptical state, out of which there is no outlet. Reasonings do not convince him; he cannot be convinced; he has no grasp of truth. Why? Because the next world is not a reality to him; it only exists in his mind in the form of certain conclusions from certain reasonings. It is but an inference; and never can be more, never can be present to his mind, until he acts, instead of arguing. Let him but act as if the next world were before him; let him but give himself to such devotional exercises as we ought to observe in the presence of an Almighty, All-holy, and All-merciful God, and it will be a rare case indeed if his difficulties do not vanish.
